"Let me be the 1st to announce that I will not be returning for a 4th season of #FallingSkies. My BSG friend David Eick will be taking over," he wrote. "I've enjoyed every minute of #FallingSkies, especially the Fans. Keep supporting the show and get ready for a cool ride starting June 9th!"

Aubuchon also confirmed that he is leaving the show in order to concentrate on writing a steampunk-themed novel.

Eick has previously worked on Battlestar Galactica as an executive producer, and was co-creator and executive producer of Caprica.

Falling Skies' third season will kick off with a special two-hour premiere on Sunday, June 9 on TNT.
